Has anyone had any luck connecting Motorola cell phones such as the StarTAC series to the built in connections on the A8? Which car kit did you use and how did you hook up the external antenna?

I have been unable to get any information from Audi on what accessories are needed for this but I am still trying. In my case I want to hook up my Nokia just like it is demonstrated in the audi manual.

Someone over there also hooked up a Nokia. It is a complex procedure and that's assuming all connections are the same. Look in the faq above for more information.
